# Financial Econometrics

### Introduksjon

Financial econometrics can be understood as the application of statistical techniques to data using the statistical programming language R (which is widely used in the financial industry) to answer questions in finance. Therefore, financial econometrics can be used to test theories in finance. As such, it is supports financial decision-making.

### Kursets innhold

• Assumption 5: Errors are normally distributed
• Multicollinearity
• Adopting the wrong functional form
• Omission of an important variable
• Inclusion of an irrelevant variable
• Parameter stability tests
